Mobilgard 1 SHC is a supreme performance, synthetic diesel engine oil formulated specifically for high power, distillate-fueled diesel engines, providing unsurpassed lubrication, long drain capability and extended engine life for marine diesel engines in severe applications. A true SAE 40 grade lubricant, it delivers stronger lubrication film strength than most SAE 50 oils on very hot engine parts, while flowing like an SAE 20W product at low temperatures, giving outstanding start-up reliability and wear protection down to -54°C; revolutionary load-carrying additives also make it an outstanding wide temperature range gear lubricant.
It is recommended as a crankcase lubricant in medium and high speed diesel engines in severe marine service, including military patrol vessels, high-speed ferries and passenger vessels, racing boats and luxury yachts, life and rescue boat engines, emergency generators, auxiliary engines, and marine gearing applications requiring FZG Level 12. It is fully compatible with conventional mineral oils and, being non-zinc, can be used with confidence in engines with silver bearing components.
Mobilgard 1 SHC carries approvals from MTU (Oil Category 2), Everllence (formerly MAN Energy Solutions) for 4-stroke medium speed distillate engines, Progress Rail and Wärtsilä 4-stroke medium speed engines, and meets or exceeds API CF and CF-2. Its synthetic, wax-free chemistry reduces oil consumption and wear while extending oil drain intervals beyond conventional oils.
Applications
Mobilgard 1 SHC is recommended for use as a crankcase lubricant in medium and high speed diesel engines in severe marine service. It is especially suited to the needs of high power concentration engines where thermal stress and loading on the lubricant are severe, as well as for applications involving low-temperature and /or frequent start-up, rapid loading following rapid start-up, and abrupt shutdown after high speed operations. Specific applications include: • Military patrol vessels, high speed ferry/passenger vessels, racing boats and luxury yachts • Life and rescue boat engines, emergency generators, auxiliary engines • Marine gearing applications where FZG Level 12 is required • Fully compatible with conventional mineral oils and mineral oil systems • Can be used in confidence in engines containing silver bearing components due to non-zinc formulation
Performance & benefits
Modern high performance, low emission, diesel engines in severe-service applications significantly increase the demands on engine lubricants. Current engine designs are tighter, reducing oil consumption and resulting in less fresh oil make-up to replenish depleted additives. Top piston rings may be located higher bringing the oil film closer to the combustion chamber where temperatures increase thermal stress on the lubricant. Higher fuel injector pressure and retarded timing improve control of exhaust emissions, but also increase engine temperatures and increase soot loads in engines operating with exhaust gas re-circulation. Mobilgard 1 SHC can provide satisfactory lubrication at temperatures significantly higher than the upper limit for other extra high performance diesel engine oils. Its inherent viscosity is SAE 40 and on very hot engine components it resists oil film breakdown better than conventional SAE 50 lubricants. The synthetic chemistry and wax free nature also provides low temperature pumpability in comparison with a conventional SAE 20W lubricant. Mobilgard 1SHC is fully compatible with conventional oils. Mobilgard 1 SHC has all the advantages of an SAE 40 weight oil without the higher oil consumption inherent in multigrade oils that use very light base stocks to achieve low temperature performance. Because of the unique molecular structure of the advanced base stocks used, combined with a highly responsive additive system, Mobilgard 1 SHC is not as volatile in the high temperature ring-belt area of the pistons in turbocharged engines. It reduces oil consumption and wear, while improving fuel economy. Mobilgard 1 SHC is also environmentally friendly in that it can significantly extend oil drain intervals beyond conventional oils which reduces waste oil di
